Product Introduction
The Parker EVM32-BASE is a DIN-rail expansion baseboard from the Compumotor 6K controller family. It houses up to four plug-in SIM boards, giving a single brick 32 additional digital or analog I/O points, and up to eight bricks can be daisy-chained off one 6K controller for larger point counts.
Plants running 6K-based motion systems use the EVM32-BASE because it is a direct architectural fit — no third-party gateway or protocol translation required. SIM boards snap into a common baseboard, so mixing digital input, digital output, and analog channels on one brick is a configuration choice, not a hardware limitation.
Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| EVM32 not recognized by 6K controller | Bad interconnect cable or loose D-sub/terminal connection | ✅ High | Reseat the 2-ft interconnect cable at both ends; inspect for bent pins | Swap cable first — cables fail more often than the baseboard itself |
| I/O point stuck on or unresponsive | Faulty SIM board, not the baseboard | ✅ Moderate | Swap the suspect SIM board into a known-good baseboard slot | If the fault follows the SIM board, replace only the SIM board |
| No response from any SIM board in the chain | 6K controller OS revision too old for installed SIM type | ❌ Low-Medium | Check 6K OS rev against SIM8-OUT-SSR / SIM8-AN-OUT requirement (rev 5.1+) | Update controller firmware before assuming hardware failure |
| Baseboard shows physical damage or missing cover | Shipping/handling damage | ❌ Low (cosmetic, not electrical) | Visual inspection of housing and vented cover | Cosmetic damage alone does not confirm electrical failure |
| Intermittent dropouts across the whole chain | Loose daisy-chain cabling or exceeded cable run length | ✅ Moderate | Inspect every cable junction in the chain, not just the last brick | Check total chain cable length against the 100-ft rated cable spec |
If you’re still stuck after these checks, send us photos of the terminal wiring and, if possible, the 6K controller’s diagnostic output — that’s usually enough for us to tell you whether it’s the brick or something upstream.

Frequently Asked Questions (FAQ)
Is this a new unit or used surplus?
This -BASE is sourced as used, functionally tested stock — not new-in-box. Given that the platform has been discontinued by the manufacturer for some time, new-condition units are essentially unavailable on the open market. What you’re paying for is a working unit with warranty backing, not factory-sealed packaging.
Can I mix digital and analog SIM boards on the same baseboard?
Yes. The baseboard is agnostic to SIM board type — you can populate it with any combination of digital input, digital output, and analog SIM boards up to four total. Just keep track of which slot holds which board, since the 6K controller addresses them by position in the chain.
Do I need a firmware update on my 6K controller for this to work?
Depends which SIM boards you’re running. The SIM8-OUT-SSR and SIM8-AN-OUT boards specifically require 6K controller OS revision 5.1 or later. If you’re running an older 6K, either update the controller OS first or stick to the standard digital/analog input and NPN/PNP output boards, which don’t carry that requirement.
How many of these can I chain together?
Up to eight bricks per 6K controller, connected in series. Each fully populated brick adds 32 I/O points, so you can scale a system significantly before you run into chain limits — just watch your total cable run length if you’re spreading bricks across a large enclosure or panel.
Will my existing SIM board configuration transfer over if I swap baseboards?
Physically, yes — SIM boards are removable and can be moved between baseboards. But document your existing SIM layout (which board is in which slot) before you pull anything. The 6K controller references I/O by chain position, so a mismatched layout after the swap will scramble your I/O mapping even though nothing is “broken.”
Why is this so much cheaper than buying new?
Because there isn’t a “new” option anymore — the platform is out of production. Pricing on this reflects used, tested secondary-market stock, which is the realistic route for this generation of Parker 6K hardware at this point.
What’s actually being tested before this ships?
To be straightforward: publicly available listings for this exact baseboard don’t spell out a documented test protocol the way some other reman programs do. If a formal test report or SOP matters for your procurement process, ask the seller directly for their inspection and test documentation before you buy — don’t assume it matches a generic “fully tested” claim without asking what that actually covers.
